DNA vs. RNA – 5 Key Differences and Comparison
WEBDec 18, 2020 · DNA is a much longer polymer than RNA. A chromosome, for example, is a single, long DNA molecule, which would be several centimetres in length when unraveled. RNA molecules are variable in length, but much shorter than long DNA polymers. A large RNA molecule might only be a few thousand base pairs long. Sugar.
Atomic Absorption Spectroscopy, Principles and Applications
WEBDec 16, 2021 · An atomic absorption spectrometer uses these basic principles and applies them in practical quantitative analysis. A typical atomic absorption spectrometer consists of four main components: the light source, the atomization system, the monochromator and the detection system (Figure 1). Figure 1: Schematic diagram of …
Genotype vs Phenotype: Examples and Definitions
WEBDec 18, 2020 · An individual’s genotype is the combination of alleles that they possess for a specific gene. An individual’s phenotype is the combination of their observable characteristics or traits. While an organism’s genotype is directly inherited from its parents, phenotype is merely influenced by genotype. Environmental factors can also affect ...
SEM vs TEM | Technology Networks
WEBFeb 25, 2020 · In SEM, the sample, located at the base of the electron column, is scanned and the resulting electron scattering is analyzed to produce an image. In TEM, the sample is placed in the middle of the microscope and electrons pass through the sample before being collected. TEM offers information on ultrathin samples' inner structure, while SEM ...

Neuroimaging Techniques and What a Brain Image Can Tell Us
WEBJul 7, 2022 · Neuroimaging is a discipline that deals with the in vivo depiction of the structure, function and pharmacology of the central nervous system (CNS), particularly our brain, in a noninvasive manner. 1, 2 The past two decades have witnessed remarkable strides in the development of new anatomical and functional imaging techniques that can shed light on many critical aspects of human brain function ...
Cell Culture Basics: Equipment, Fundamentals and Protocols
WEBMay 5, 2021 · Cell culture refers to the removal of cells from an animal or plant and subsequent cultivation in an artificial environment for scientific research. The first cell culture techniques were developed over 100 years ago and since then have contributed to tremendous breakthroughs in science. Today, it is a fundamental tool used in laboratories ...
What are Progenitor Cells? Exploring Neural ... - Technology …
WEBDec 18, 2020 · Stem cells share two qualifying characteristics. Firstly, all stem cells have the potential to differentiate into multiple types of cells. Secondly, stem cells are capable of unlimited self-replication via asymmetric cell division, a process known as self-renewal. There are two broad categories of stem cells found in all mammals.
RNA-Seq: Basics, Applications and Protocol | Technology Networks
WEBApr 6, 2018 · RNA-seq (RNA-sequencing) is a technique that can examine the quantity and sequences of RNA in a sample using next-generation sequencing (NGS). It analyzes the transcriptome, indicating which of the genes encoded in our DNA are turned on or off and to what extent. Here, we look at why RNA-seq is useful, …
An Overview of Next-Generation Sequencing | Technology Networks
WEBMar 17, 2021 · Whole genome sequencing (WGS) is the most widely used form of NGS and refers to the analysis of the entire nucleotide sequence of a genome. Whole exome sequencing (WES) on the other hand is a form of targeted sequencing that only addresses the protein coding exons. In humans, this accounts for only around 2% of the genome and consequently offers an opportunity for a greater depth of study in ...
